This invention relates to a vending machine for valve cores used in thevalve stems of pneumatic tires and the like, the general object of theinvention being to provide 5 means whereby a customer can secure a coreby depositing a coinof the proper denomination into the machine andturning the handle of the machine.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand speciically pointed outv in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several yieWS, and in which F igure 1is a. front view of the device, showing the interior parts in dottedlines.

Figure 2 is a section on line 2 2 of Figure l.

Figure 3 is a top plan View.

Figure 4 is a viewy similar to Figure 1, butshowing the interior partsin a different position. l

Figure 5 is a Section on line 5 5 of vFigure 2.

In these views, the numeral 1 indicates a casing which is divided by thepartitions 2 into a large chamberand a small chamber. An inclined rack 3is arranged in the large chamber, the rack comprising two members spacedapart to receive the cores, shown at A, between them, and as shown, thecores are held in upright position and they will gravitate toward thelower end of the rack.

A lever 4 has its upper end pivoted to a stub shaft 5 carried by thevertical partition 2, the lever being arranged within the large chamber,and the lower end of the lever is formed with the curved prongs 6 and 7.

The upper portionsof the prongs are bent outwardly in oppositedirections from the stem so that said prongs are spaced .apart and theextremities of the prongs overlap.

The lever is so arranged that its prongs 7 58 will extend across thepath of the cores and thus prevent the cores from moving onfthe rack,but when the lever is moved to the right, the prong 7 will move out ofthe path of the vcores and the prong 6 will be in the path of the coresand as the prongs are spaced apart a distance slightly greater than thediameter of the core, one of the cores will ymove intothe space betweenthe prongs and be heldby lthe prong 6. Then when the lever is moved tothele'ft, the prong 6 will Ire- 60 lease the first core so that thiscorecan drop from the rack, but vthe core next to the first one -willbeengaged by the prong 7, So that but Zone corecan drop from the rack.Thus the oscillation ofthe lever controls the'dis- 65 charge of thecores from the rack and per-l mitlslbutf one core at a time to drop fromthe rac f A "A `shaft 8 is journaled in the walls Vof the front or smallchamber,with itsrear end 7o' passing through the vertical partition 2and links 9 'connect this shaft with `the upper part of -thelever 4. Anarm 10 is fastened to the shaft and extends,downwardlyV into engagementwith the periphery of a disk 11 75 fastened toa shaft 12 which is alsojournaled in the' walls of the small chamber and extends through thefront wall where it receives a knob 13. The disk has a coin receivingnotch 14 therein which, when the disk is in a cerso tain position,will'be located below the lower end of a coin chute 15 which dependsfrom the top of the casing, so that a coin .dropped into the chute willenter the notch with a portion projecting above the disk, so that whenthe disk is turned, this portion of the coin will contact the arm 10,thus pushing the arm outwardly. This movement of the arm will partlyrotate the shaft 8 and causeA vthe links 9 to move the lever 4 to aposition :19.0

where the prong 6 will release a core. `lhen the disk is turned to aposition to move the coin out of contact with the arm 10, a spring 16,which engages the lever, will return the parts to normal position. Thecoin will v finally drop from the notch into the bottom of the smallchamber, from which the coins can be removed by opening the door 17 inthe front of the chamber, this door being provided with a lock 18.Ratchet means,-.i f

shown generally at 19, prevent retrograde movement of the disk and theshaft 12 and the cores dropping from the rack, will fallv upon a chute2O which will deliver the cores to a tray 2l at the front of the casing.

The top 22 of the casing is removable so that cores cany be placed onthe rack and this top is secured in position by the lock 23.V

Y.aus

From the foregoing it will be seen that I have provided simple meanswhereby one can secure a valve core by depositing acoin in the deviceand turning the handle. The device can be placed anywhere desirable,such for instance, on -an exterior wall of a garage7 so that thecustomers can secure valve cores without going into the garage and evenif the-garage is closed. A Y 1 v ItA is thought from the foregoingdescription that the advantages and novel features of the invention willbe readily apparent.

It is to be understood that changes may be made in the constructiony andinthe combination and arrangementy of the several parts, provided thatsuch Changes fall within the scope of the appended claim.

Vhat I claim is A A dispensing ydevice of the class described comprisinga diagonally arranged rack for holding the articles to Ybe vended, ayforked lever pivotally supported andV having its prongs curving towardeach other,l with the Y prongs bent outwardly in opposite directionsbeyond the longitudinal plane of the lever,

#with the extremities of the prongsoverlapping, the lower endrof therack extending betweenthe prongs and means for oscillating the lever torelease the lowestY varticle on the rack while holding the next Varticleon the rack.

In testimony whereof I aflix my signa-ture.
